COMBINATION INSTRUMENT. V

Application filed Hove nber 9, 1922. Serial No. 599,785.

To all whom z't-may concern I Be it known that I, GEORGE TURKOVIGH, a citizen of the United States, and resident of lVest Allis, in thecounty of Milwaukee and State of l/Visconsin, have invented certain new and useful Improvements in Combination Instruments; and I do herebydeclare' that the following is a full, clear, and exact description thereof.

This invention relates to combination instruments and is particularly directed to a combination compass or an instrument of this general character.

Objects of this invention are to provide a device which may be easily changed from a pair of dividers into a compass with either a penor pencil marker; to provide an instrument in which one portion of the pen marker is used as one of the compass points and to provide a device which is especially adapted for machinists and wood workers, and is therefore adapted to be freely carried in the overalls of such workers without harming any portion of the instrument.

Further objects are to provide a combination instrument which may be readily produced in a cheap and simple manner, and to provide an instrument whose parts may be formed from standard material.

An embodiment of the invention is shown in the accompanying drawings, in which- Figure 1 is a side elevation of the device.

'Figure2 is a fragmentary view showing certain of the parts in section and illustrating in detail one leg of the instrument.

Figure 3 is a sectional view on the line 33 of Figure 2.

Referring more particularly to the drawings, it will be seen that the instrument is provided with a pair of arms 1 and 2, which are pivot-ally associated by means of a member 3, and are provided with the usual bowed spring 4. tending to open the arms outwardly. The arm 2 has pivoted therein, the adj usting screw 5 which passes thru an eyelet 6 pivoted to the arm 1 and is provided with any type of quick or slow adjusting nut 7 upon its extended portion.

The arm 1 is provided with the usual pointed terminal 8, while the arm 2 is out off, as indicated at 9, along a curved line at a point slightly above the end of the arm 1.

A folded member 10 of generally U-shaped I cross section encloses the lower portion of the arm 2 and is riveted thereto as indicated instrumentalities.

lated, thereby at 11. It is provided with an upper hous ing 12 and a lower housing 13, within which are slidably mounted the various marking The housing 12 is provided with an elongated'slot 14 thru each face thereof, within which is fitted a relatively small cross head 15 provided with a slot 16 having rounded juxtaposed faces.

This cross head, as will be seen, from Figure 3, projects laterally beyond the margins grip for adjusting the instrument. A strip of spring material is folded thru the slot 16, as may be seen from Figure 2, and has a relatively long'outer arm 17 and a relatively V shorter inner arm 18 spring pressed against the face of the leg 2, so as to force the arm .17 outwardly, The lower portion of the arm 17 is provided with a pointed extremity 19, and with a bowed'portion 20. A corof the housing 12 so as to provide a finger' The operation of the apparatus is as follows :--When itis desired to use the device as an ink compass, the partsare arranged, as shown in Figure 2, and ink is placed between the bowed portions 20 and 21. When, however. it is desired to use the deviceas a pair of dividers, the handle, or projection, 23, is forced upwardly thereby" drawing the slide 22 into the dotted line position shown in Figure 2 and leaving the pointed extremitv 19 of the arm 17 projecting. This provides a point which cooperates with the point 8 of the arm 1, to adapt the instrument for use as a pair of dividers.

When it is desired to use the device as a pencil compass, the cross head 15 is moved upwardly into the position shown in Figure 1, thereby moving the pen and point portion upwardly above the point of the lead 24:. It has been found that the frictional engagement between the slide 22 and the arm. 17 is such that these arms will travel upwardly together when the cross head 15 is manipuleaving the lead in position" for use.

It will thus be seen that a combination pencil and ink compass and dividers has been provided which may be readily manipulated, which may be cheaply produced, and which is of sturdy and rugged design.

I claim:

l. A combination compass and dividers comprising a pair of pivotally mounted adjustable arms, one of such arms being pointed, a housing secured to the other arm, a lead positioned Within such housing, a. folded spring member positioned within said housing and having one arm pointed and resiliently pressed towards said lead and the other arm resiliently pressed, against said second mentioned pivoted arm.

2. A combination instrument comprising a pair of pivoted adjustable arms, one of such arms being pointed, a, housing secured tothe other of said arms, a lead carried within said housing, a folded spring member having a pointed bowed end positioned within said housing and adapted to be pro-- jected beyond said lead, and a second bowed member slidably mounted in said housing and adapted to cooperate with said bowed portion to form an ink pen. 7

In testimony that I claim the foregoing I have hereunto set my hand at West Allis,

in the county of Milwaukee and State of WVisconsin.
